Specification of Letters Patent.

Patented Dec. 2c, 1919.

Application filed October 20, 1919. Serial No. 331,999.

To all whom it may concern Be it known that I, EMIL HUBER, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented new and useful Improvements in Machines for Straightening the Weft-Threads of Textile Piece Goods, of which the following is a specification. a

This invention relates to an improvement in machinery for straightening the weft, threads of silk, cotton, woolen and other piece goods, its object being to simplify the construction of such machinery by dispensing with a multiplicity of actuating rollers and the complication of mechanism for ad justing and driving the same.

In rolling or handling such goods after leaving the loom the warp and weft threads are liable to become distortedwith respect to each other, thus marring appearance and lessening value; and the principal object of my invention is to restore the threads to the exact angular relation with respect to each other which they occupied at the time when the fabric left the loom. Other advantages of my improvement consist in its reduction of cost of installation andnse, its strength and durability, and the facility with which it may be worked by unskilled labor.

In the accompanying drawings,

Figure 1 is afront elevation of my improved machine, and showing the passage of a piece of fabric therethrough for straightening out the weft threads. Fig. 2 is an end elevation viewed from the left of Fig. 1, and Fig. 3 is a similar view from the right of said figure.

In the description given herein the machine is supposed to be erected in general vertical position, but it is obvious that it may be arranged horizontally, that is to say, tablewise, if so required. 7

1 and 2 are the main standards, they having suitable feet as shown. The standards 1, 2 are connected near their bases by a horizontal member 3 bolted thereto. 10 and 14 are the actuating rolls more particularly hereinafter described as to arrangement and function, they being the only operative rolls required.

4, 5 indicate supports or brackets secured horizontally to the standard 1, and '4, 5 similar supports bolted to the standard 2. The supports 4, 5 of the standard 1 are in parallel relation to each other, as also are with a hand wheel 8.

the supports 4*, 5 of the standard 2, although the latter support is nearer to its fellow 4 than is the support 5 to its fellow 4 of the standard 1.

The support 5 has integral therewith two projecting parts 6, 6, between which is a vertical slideway7. The support 4 is furnished with projecting parts 6 transversely arranged with respect to the projections 6, 6 of the support 5, a horizontal slideway 7 being formed. The projections 6, 6 and 6 6 are provided with longitudinal grooves 6 and 6, respectively. Longitudinally movable within the vertical slideway 7 is a journal box or bearing 8 provided with studs or guide blocks 8 which enter the grooves 6 this box or hearing 8 constituting the journal for one end of the lower vertically adjustable roll 14. Connected with the box 8 and at the under side thereof is a cap plate 8 having within it a seat for the'head 8 of the adjusting screw 9, the latter being threaded in the support 5 at 8, and provided Thus the box 8 has vertical and sliding movement in the way 7, and also a tilting or twisting movement on its studs or guide blocks 8 in the grooves 6".

The upper support 4 is provided with a similar box 11 having studs or guide blocks 11 which slide horizontally in the grooves 6, and also with a cap plate 1l like to that 8 -in which is similarly arranged the head of an adjusting screw 12 having a hand wheel 13, this screw being threaded in the yoke 15 bolted to the projections 6 The box 11, therefore, is adapted to be given horizontal movement in the slideway 7 and also is capable of twisting or oscillatory or tilting movement on its studs 11".

By referring to Fig. 1 it will be seen that the roll 10 lies in a horizontal plane, while the roll 14 occupies an angular position with respect to its companion roll, its ability to assume such or other inclined position-due to the action of the screw 9being provided for by its described journal boxes.

Figs. 1 and 3 show in addition to the standard 2 and its supports 4*, 5, the journal boxes 11 and 8, these boxes having studs or trunnions set in suitable bearings as indicated, whereby to permit the tilting or free ter of the fabric to be treated.

shafts may be provided with retaining or spacing collars held thereto by set screws as seen in Fig. 1.

In operation, the fabric having been put over the upper roll 10 and under the lower roll 14:, the observation of the operator will indicate to him what adjustments of either roll or both rolls are necessary to effect the desired results. Such adjustments will depend upon the extent of distortion of the weft threads, and perhaps upon the charac- Any degree of inward or outward movement at one end of the roll 10 is obtained by the use of the handwheel 13, while any required obliquity or twist of the roll is provided for by the swivel bearings described. Similar adjustment of the lower roll 14 is permissible by the use of the hand wheel 8*, and the pro vision of the swivel bearings described. Worm gear or other well known equivalent connections I may be substituted for the screws shown for effecting the adjustment of the operating rolls.

Veryshort experience in the use of this machine will instruct the operator as to the nature and nicety of the adjustments needed for the different classes of fabrics to be operated upon. When the fabric running through such machine is straight the rolls of I my plaid straightener are arranged parallel with those of said machine, but when crooked the two rolls of the latter are ad usted in the required manner to straighten out the goods, which may either wet or dry.

My textile fabric tentering or stretching machine, as will be understood, has no driving means of its own, the fabric beingdragged or conducted therethrough, and may be used as an adjunct to or part of any machine as a plaid or fabric straightener, thus requiring no additional or separate floor While I have mentioned textile piece fabric as the article specially intended to be acted upon by my machine. it is obvious that printed or figured goods in piece, such as flags, handkerchiefs or other articles of like character may be run through for straightening out'the lines or irregularities of the print, my machine being capable of use upon any material in which crooked or irregular threads or lines are to be adjusted.

An important advantage of my construction arises from the comparatively large size ofthe rollers, which may be from six to eight inches, or more, in diameter. The larger the roller used the lesser is the number of rollers required, as I'have demonstrated, and lesser and simpler necessarily is the adjustment needed.

I claim:

1. In a fabric tentering or stretching machine, two spaced rolls and bearings for the same, one of said rolls having at one end-a bearing capable of horizontal sliding movement and at its other end a bearing capable of swiveled movement; and the othenroll having at one end a bearing cap-able of vertical sliding movement and at its opposite end a. bearing capable of swiveled movement.

2. In a fabric tentering or stretching machine, two' standards; an upper and a lower pair of supports carried byeach of said standards; a horizontally sliding and ad justable journal boxin one of said upper supports, and a swiveled journal box inits companion or opposite upper support; a vertically sliding and adjustable journal box in one of said lower supports, and a swiveled journal box in its companion or opposite lower support; a roll carried by said upper journal boxes, and another roll carriedby said lower journal boxes.

In testimony whereof I affix my signature.

EMIL HUBER.
